Tectonically active zone in Himalayas


Newly identified tectonically active zone in Himalayas could alter earthquake study & predictions

      WHY IN NEWS:

The study was published recently in the journal ‘Technophysics’.

MINISTRY? :- Ministry of Science & Technology


The suture zone of the Himalayas or the Indus Suture Zone (ISZ) in the Ladakh region where Indian and Asian Plates are joined has been found to be tectonically active, as against current understanding that it is a locked zone.



  • This could have major impact in terms of earthquake study, prediction, understanding the seismic structure of the mountain chains well as its evolution.
  • Researchers carried out the mapping of the remote regions of Ladakh that forms the most hinterland part of the Himalaya.


  • The geologists observed that sedimentary beds are tilted and thrust broken.
  • The rivers are associated with uplifted terraces, and the bedrock shows brittle deformation that occurred at much shallower depths.

These deformed geological features were then dated in the laboratory at Dehradun using a technique called Optically Stimulated Luminescence (OSL).

It is a method for carrying Luminescence dating of geological sediments and data of seismicity and denudation rate review.

  • The combination of field and lab data suggested the region of the Indus Suture Zone (ISZ) has been neo-tectonically active since the last 78000 — 58000 years.
  • A recent earthquake in 2010 of low magnitude 4.0 near the village of Upshi that occurred due to a thrust rupture.

      IASbhai WINDUP: 

Himalaya were known to be made up of north dipping thrusts like the Main Central Thrust (MCT), the Main Boundary Thrust (MBT), and the Main Frontal Thrust (MFT).

  • As per the established models, all of these thrusts except MFT are locked, and overall deformation in Himalaya is being accommodated only along with the MFT.

Amur falcons : ‘Birds of God’


Once target of mass hunting in Northeast, ‘Birds of God’ are now rare symbol of hope

      WHY IN NEWS:

There has never been such a quick turnaround to a conservation project in India, where one year a species was being hunted and in the next, it stopped.

SYLLABUS COVERED: GS 3: Conservation of Flora and Fauna


What has made the project a true success was the involvement of the community.


  • The mass harvesting of the bird — with one of the longest migratory routes, from Siberia to Africa — prompted governments, and wildlife experts, to launch a desperate conservation project.
  • After the hunt, the bird would be sold for Rs 25-30 a piece in markets, with a hunter earning anywhere between Rs 30,000-50,000 in a season.
  • Eight years ago, reports of around 1 lakh Amur falcons being hunted every day in Nagaland’s Wokha district, to be sold for their meat, had created a flutter across the world.

27th Oct Current Affairs News Analysis

  • From breeding grounds in Siberia and northern China, these falcons migrate west, across the Arabian Sea, to Southern Africa, where they spend the winters.

For a period of about 10 years, during their brief stopover, around 15,000 birds were being harvested every day in Wokha.

  • Sometimes, experts say, the numbers even went up to 1 lakh a day.
  • In the far-off Tamenglong district of Manipur, Amur falcons had been hunted for 40 years.
  • But their ancestors believed that these were sacred birds.
  • They were called Ra Ruai or Birds of God.

They believed that whenever they arrived in large numbers, it would portend a good harvest. 

  • We reminded our people of our ancestral beliefs, and explained how important the birds were for the biodiversity of the area.
  • The Church pointed out that conservation of wildlife was also mentioned in the Bible.


27th Oct Current Affairs News Analysis

  • Amur Falcon is a small raptor of the falcon family.
  • Its a small, slender, pigeon-sized bird of prey, and is noteworthy for undertaking one of the longest and most arduous annual migrations of any bird of prey.

It breeds in south-eastern Siberia and Northern China before migrating in large flocks across India and over the Arabian Sea to winter in Southern Africa.

  • Males are dark grey with reddish brown thighs and undertail coverts; reddish orange eye-ring, cere, and feet.
  • Females are duller above, with dark scaly markings on white underparts, an orange eye ring, cere, and legs.

Their diet consists mainly of insects, such as termites; during migration over the sea, they are thought to feed on migrating dragonflies.

Moon : Water water everywhere


On the moon, water water everywhere and not a drop to drink

      WHY IN NEWS:

A team led by Casey Honniball of NASA’s Goddard Space Flight Center in Maryland detected molecular water on the lunar surface, trapped within natural glasses or between debris grains.



The moon lacks the bodies of liquid water that are a hallmark of Earth but scientists said on Monday lunar water is more widespread than previously known

27th Oct Current Affairs News Analysis Moon

A total lunar eclipse, also known as a “blood moon“.

  • The water molecules trapped within mineral grains on the surface and more water perhaps hidden in ice patches residing in permanent shadows.
  • While research 11 years ago indicated water was relatively widespread in small amounts on the moon.

A team of scientists is now reporting the first unambiguous detection of water molecules on the lunar surface.


  • Water is a precious resource and a relatively plentiful on lunar surface .
  • Its presence could prove important to future astronaut and robotic missions seeking to extract and utilize water for purposes such as a drinking supply or a fuel ingredient.

Previous observations have suffered from ambiguity between water and its molecular cousin hydroxyl, but the new detection used a method that yielded unambiguous findings. 

  • The only way for this water to survive on the sunlit lunar surfaces where it was observed was to be embedded within mineral grains, protecting it from the frigid and foreboding environment.
  • The researchers used data from the SOFIA airborne observatory, a Boeing 747SP aircraft modified to carry a telescope.

27th Oct Current Affairs News Analysis Moon

 A high resolution mosaic of our moon’s north polar region is seen in this undated handout image taken by scientists using cameras aboard NASA’s Lunar Reconnaissance Orbiter (LRO).

  • The study focused upon so-called cold traps on the moon, regions of its surface that exist in a state of perpetual darkness where temperatures are below about negative 260 degrees Fahrenheit (negative 163 degrees Celsius).
  • That is cold enough that frozen water can remain stable for billions of years.

      IASbhai WINDUP: 


  • Another mystery that remains unsolved is the source of the lunar water.
  • Currently, the major contenders are comets, asteroids or small interplanetary dust particles, the solar wind, and the moon itself through outgassing from volcanic eruptions.
  • Earth is a wet world, with vast salty oceans, large freshwater lakes and ice caps that serve as water reservoirs.
  • As our closest planetary companion, understanding the origins of water on the moon can also shed light on the origins of Earth’s water – still an open question in planetary science.
